Yes. As long as the two halves of the broken key are available, a locksmith can generally translate the bitting and cut a fresh, one-piece replacement.

For a standard house key, the process takes less than five minutes. For a modern-day transponder or clever key, the procedure typically takes 20 to 60 minutes, depending on how long the automobile's computer takes to "handshake" with the new hardware.
5. Is it possible to program a car key personally?
Some older lorries (primarily pre-2010 American models) have "on-board shows" series that owners can carry out. Nevertheless, most modern-day cars need a connection to an OBD-II (On-Board Diagnostics) port through a specialized computer, which is not accessible to the average consumer.
